Kim Kardashian and her sister Kourtney's boyfriend Scott Disick have one fan they reportedly fear may be dangerous.

Kardashian, 31, and Disick, 29, reportedly received a letter from a fan who dropped the note off at the latter's RYU restaurant in New York City. While the letter was addressed to Disick it was reportedly meant to be read by both of the reality television stars, according to "Wetpaint Entertainment."

"I would like to meet you and Kim at Little Ferry Public Library [in New Jersey]. The parking lot is in the back on Redneck Road. Wells Fargo bank is next door. I will be there September 29, 2012 from 1130am to 130pm," the letter addressed to Disick read. "There is a table next to computers 7 and 8 or you can sit by the corner. You can wear sunglasses or you can walk up to me with your glasses on and hand this note. Then I will know and we'll leave the library."

In the letter, the mystery fan told Kardashian that she would already know what they look like and instructed the pair in detail about which outfits they should choose.

"I will give you more gigs. Kim, you know what I look like," the letter read. "I will be wearing a green and black shirt. You can wear all white. No makeup."

While Disick refused to meet the mystery fan, he reportedly decided to give the New York Police Department the note left at his restaurant. The letter is reportedly under investigation by the department.

In a recent interview with Sky News, Kardashian opened up about how hectic it can be to have both fans and haters. In the interview, Kardashian said she has had to endure some people saying ridiculous things to her.

"I try not to pay attention to it but when I'm on Twitter and I see things that people say sometimes, I'm so shocked at the things that they say. I mean it's people that don't even know you, they can say ridiculous things," Kardashian told Sky News. "Obviously you feel it and it hurts sometimes, but you try not to pay too much attention to it. I feel sad that someone feels so much anger for someone they don't even know."
